Variable ALT tags for Uploaded Images

Ce fil est résolu. Voici une description du problème et la solution proposée.

Problem:

I've been investigating how to populate ALT tags for images without having to do it manually via the media library every time an image is uploaded. I had thought about having a custom field that could be populated with other post data when the form is submitted to create tags that follow a consistent format.

Solution:

You can setup the image HTML tag manually, for example:

[types field='image-1' alt='Christmas Part 2018' size='full'][/types]

but this doesn't:-

[types field='image-1' alt='[types field='image-alt'][/types]' size='full'][/types]

My question therefore is how do I populate the alt text field in the media library when the form to create the post containing the images is submitted?

Thank you!

Hello,

You can setup the image HTML tag manually, for example:

<img src="[types field='image-1' size='full' url='true'][/types]" alt="[types field='image-alt'][/types]" />

More help:
https://toolset.com/documentation/customizing-sites-using-php/functions/#image
url:
'false'(default) | 'true'
true=output the url of the image instead of the html img tag.

Hi Luo

The alt content for the image still isn't being returned with your code (I can't see it using Page Source in dev tools). However if I change alt="[types field='image-alt'][/types]" to alt="[types field='image-alt' url='true'][/types]", it does.

Thanks for pointing me in the right direction.
